Spring-security中的UserDetails @Autowired返回異常

請告訴我我在哪裏有問題？這裏是我的項目：https://github.com/intrade/inventory 我嘗試使用Java的配置，使春天的安全，當我嘗試注入MyCustomUserDetailsService類型的依賴到my SecurityConfig class我得到一個異常：Spring-security中的UserDetails @Autowired返回異常

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'securityConfig': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.springapp.mvc.services.MyCustomUserDetailsService com.springapp.mvc.InitApp.SecurityConfig.myCustomUserDetailsService; nested exception is java.lang.IllegalArgumentException: Can not set com.springapp.mvc.services.MyCustomUserDetailsService field com.springapp.mvc.InitApp.SecurityConfig.myCustomUserDetailsService to com.sun.proxy.$Proxy38

您試圖按類自動裝載您的用戶詳細信息服務，但這不起作用，因爲spring bean實際上是圍繞該類（而不是該類的實例）創建的代理。然而代理將實現原始bean的所有接口，所以通過接口注入是安全的。

交易所這一行：

@Autowired 
private MyCustomUserDetailsService myCustomUserDetailsService;

這一個：

@Autowired 
private UserDetailsService myCustomUserDetailsService;

閱讀Spring AOP的上Proxying Mechanisms部分，瞭解詳細信息。

謝謝！可能是你可以讓我更多的問題？我有新的例外： org.springframework.beans.factory.BeanCreationException：在類路徑資源[org/springframework/security/config/annotation/web/configuration/WebSecurityConfiguration.class]中定義創建名稱爲'springSecurityFilterChain'的bean時出錯： bean的實例化失敗;嵌套異常是org.springframework.beans.factory.BeanDefinitionStoreException：工廠方法[公共javax.servlet.Filter org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration.springSecurityFilterChain（） –

@AleksandrsRudzitis我需要更多信息（完整堆棧跟蹤）。要麼提出一個新問題，要麼直接與我聯繫（請參閱我的個人資料頁面） –
